• Implement an income summary showing total income and income trends.
• Display a chart to visualise income sources over time.
• Allow users to mark recurring incomes (e.g., salary, dividends).
• Ensure authentication is required for all income-related actions.

Acceptance Criteria:

• Users can view a list of their income transactions with correct details.
• Users can add a new income record, specifying source, amount, date, and notes.
• Users can edit or delete existing income transactions.
• The income summary correctly displays total income for the selected period.
• The income trends chart accurately reflects income distribution.
• Filtering and sorting work correctly (by date, source, amount).
• Recurring income transactions are saved and displayed properly.
• API requests require authentication and return appropriate errors if unauthorised.
